I recently upgraded my pc to windows 7. On my old 32bit machine I used to be able to run DVD43 in the background and use Handbrake to rip a DVD into iPhone format? DVD43 doesn't work on Windows 7 64 bit. So what's the best way to rip the DVDs I want into iPhone format on my Windows 7 64 bit machine?
I've worked around things like this by using Xp Mode. Just install the software in 32bit Xp Mode and, if necessary, transfer control of any hardware to Xp Mode. Sometimes Xp Mode needs exclusive access to the hardware. For example, I used Xp Mode to install a 32bit printer driver and access an old printer: http://aaronls.wordpress.com/2009/10/29/no-windows-7-driver-for-your-printer-use-xp-mode/
If you don't have an edition of Windows 7 that support Xp Mode, you can just use VirtualPC.
I went with DVDDecrypter. Although it does not work exactly the same way that DVD43 does because it does not allow Handbrake to rip directly from the DVD. Instead, I used DVDDecrypter to rip the DVD to a folder on one of the disk drives, and Handbrake was able to successfully read the ripped folder.
Although it is not the perfect "DVD43 Experience", it is a freeware solution for anyone who does not want to use XP Mode.
You can use handbrake with VLC's libdvdcss (free) in windows 64 bit (it's 32-bit but seems to work fine). https://forum.handbrake.fr/viewtopic.php?f=11&t=16670#p78021
update: "Second, they tell you to rename libdvdcss-2.dll by removing the '-2' from the filename. This no longer works." (just leave it named the same these days apparently) ref: http://grandiloquentmusings.blogspot.com/2014/12/ripping-encrypted-dvds-with-handbrake.html
SlySoft AnyDVD will transparently decrypt DVDs on the fly and some other cool things. It works well with Handbrake. However, it is not free.
A free alternative is passkey for DVD. It is the free version of DVDFab, and it's working very nicely on a windows 7 install in place of an old handbrake+dvd43 setup I used to have.
